MED MODIFIED A+ CRANKSHAFT

Due to popular demand, MED re-worked crankshafts are back, for 1275 engines with A-plus (1.750") big ends. These are based on brand new Rover crankshafts, modified for high performance road and trackday engines.

Specifications

• Std/std journal sizes

• Heat treated journals

• Cross-drilled mains

• Wedged to improve counterbalance and reduce weight

• Balanced dynamically to within 1g

The crankshafts are CNC-machined to improve counterbalance and also reduce overall weight. More specifically, we've re-profiled the web around the big end journal area, where this has the most effect.

Once machined and balanced, we have a ni-temper treatment applied before a specialist polish and quench technique to improve journal durability.  

Modified using decades of A-Series engine experience.

Available separately or as a complete kit with ACL main bearings, big end bearings and thrust washers to suit.

The crankshafts are genuine original Rover items, so you may find minor imperfections on the surfaces. Rest assured that any marks are superficial only and will not affect performance or longevity of the crankshafts.
